本书第二部分讲述的是在Wi n 3 2平台上的Wi n s o c k编程。对于众多的基层网络协议， Wi n s o c k是访问它们的首选接口。而且在每个Wi n 3 2平台上，Wi n s o c k都以不同的形式存在着。 Wi n s o c k是网络编程接口，而不是协议。它从U n i x平台的B e r k e l e y（B S D）套接字方案借鉴了 许多东西，后者能访问多种网络协议。在Wi n 3 2环境中，Wi n s o c k接口最终成为一个真正的 “与协议无关”接口，尤其是在Winsock 2发布之后。

All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.)

ACM试题An Easy Problem Description As we known, data stored in the computers is in binary form. The problem we discuss now is about the positive integers and its binary form. Given a positive integer I, you task is to find out an integer J, which is the minimum integer greater than I, and the number of 1 s in whose binary form is the same as that in the binary form of I. For example, if "78" is given, we can write out its binary form, "1001110". This binary form has 4 1 s. The minimum integer, which is greater than "1001110" and also contains 4 1 s, is "1010011", i.e. "83", so you should output "83".

OpenSG is a scenegraph system for realtime rendering, e.g. for Virtual Reality applications. It is just a library, not a full application. This documentation contains descriptions of the internal classes and concepts, as well as a tutorial that explains how to use the system.
